Cochlear Nucleus 6 (CP900) Microphone Covers & Tool Replacement

The Cochlear Nucleus 6 CP910 Microphone Cover is a replacement microphone protector set for Nucleus 6 sound processors, supplied with a removal tool. It fits the CP910 and the CP920. Each cover sits over one of the processor microphone openings, keeping out dust, sweat and moisture while letting sound through, and the tool lets you lift the old covers out without scratching the processor.

Cochlear documents often call these parts microphone protectors, while most wearers simply say mic covers; both mean the same thing. On this page you will find the fit check, the warning signs of clogged covers, how to use the removal tool step by step, a troubleshooting table and practical care tips.

The removal tool is what sets this pack apart. Nucleus 6 covers sit snugly in the processor, and prying them out with a fingernail or a sharp object can mark the housing or push debris inward. With the tool, changing a Cochlear Nucleus 6 CP910 Microphone Cover becomes a quick, low-risk job you can do at the kitchen table.

Will this Cochlear Nucleus 6 CP910 Microphone Cover fit my processor?

Your processor	Does it fit?	What to choose
Nucleus 6 CP910	Yes	This pack
Nucleus 6 CP920	Yes	This pack
Nucleus 5 (CP810 / CP802)	No	Our Nucleus 5 microphone covers
Nucleus 7 (CP1000)	No	Our Nucleus 7 microphone covers

Your model name, CP910 or CP920, is printed on the processor and recorded in your clinic file. Both are Nucleus 6 CP900 series processors and both take these covers, even though the product name mentions the CP910.

Each processor generation has covers of its own shape. A cover meant for a Nucleus 5 or Nucleus 7 will not sit flush on a Nucleus 6, so it may let dirt in or drop out during the day.

If you bought a used Nucleus 6 or have been handed one down, fit fresh covers before judging how it sounds. Old, blocked protectors on a second-hand processor can make a perfectly good unit seem weak or muffled.

Why Nucleus 6 wearers should not skip cover changes

Nucleus 6 processors adjust automatically to different listening scenes and offer directional settings that help you focus on the person in front of you. Those settings depend on both microphones receiving sound evenly. When one protector clogs faster than the other, that balance is lost and speech in noise can suffer.

Because the N6 is now an older processor, keeping its microphones in good condition is also a matter of protecting a device you may want to wear for years to come. A fresh Cochlear Nucleus 6 CP910 Microphone Cover costs little compared with a microphone repair.

Changing a Cochlear Nucleus 6 CP910 Microphone Cover is also a good moment to look over the rest of the processor: check the coil cable for wear, the battery contacts for dirt, and the processor case for cracks. A few minutes of attention helps the whole system last.

Signs your Nucleus 6 microphone protectors are clogged

• Speech sounds muffled or as if people are talking from another room.
• Restaurants and meetings feel harder than they used to.
• Music sounds flat or lacks its usual sparkle.
• One processor of a bilateral pair sounds duller than the other.
• Sound became dull after a humid day, sport or rain.
• The protectors look grey, discoloured or have visible fluff in them.

These changes happen slowly, so many wearers do not notice them until they fit a new Cochlear Nucleus 6 CP910 Microphone Cover and suddenly hear the difference. If in doubt, change them and compare.

Where you live and work also plays a part. Dust, kitchen steam, workshop particles, sea air and high humidity all clog covers faster. If any of these are part of your day, check your N6 mic covers more often than the average wearer would.

How to change your Cochlear Nucleus 6 CP910 Microphone Cover with the removal tool

1. Switch the CP910 or CP920 off and take it off your ear.
2. Rest it on a clean towel so small parts cannot roll away.
3. Place the tip of the removal tool at the edge of the first old protector.
4. Lever gently to lift the protector out; do not push the tool into the microphone opening.
5. Brush away any loose dust around the opening with a soft, dry brush.
6. Place a new protector over the opening, correct side up.
7. Press with a clean fingertip until it sits evenly and flush.
8. Repeat for the second microphone.
9. Switch on and do a listening check in a quiet room.

Keep the removal tool with your spare covers. It is small and easily lost, and it makes every future change easier.

If a protector is stuck, do not force it. Work the tool tip around the edge a little at a time until it lifts. Pressing hard in one spot can bend the tool or push the old cover deeper into the opening.

Nucleus 6 microphone cover troubleshooting

What you notice	Likely cause	What to do
Sound still dull after changing	Cover not fully seated, or the wrong program	Press evenly around the edge; check your program
Cover falls out within a day	Cover not pressed home, or wrong cover type	Refit it firmly; confirm your model is CP910 or CP920
Crackling or wind-like noise	Cover lifted at one edge	Remove and refit, or use a new cover
One side duller than the other	Covers changed on one processor only	Change covers on both processors
No sound at all	Not caused by the covers	Check the battery and the N6 coil cable

A Cochlear Nucleus 6 CP910 Microphone Cover affects the clarity of sound, not whether the processor works. Silence points to the battery, the coil cable or the processor itself.

How to make your Cochlear Nucleus 6 CP910 Microphone Cover last longer

• Put on hair products, sunscreen and perfume before the processor, and let them dry.
• Take the processor off for swimming, showers and very sweaty exercise unless it has suitable water protection fitted.
• Dry the processor overnight in an electric dryer.
• Avoid wiping across the covers with a damp or oily cloth.
• Store the processor in its case when it is not on your ear.
• Check the covers each week in good light.

Covers are a routine consumable. Many clinics suggest changing them every few months, or sooner if they look dirty or sound seems muffled.

Writing the date on the bag of spares each time you fit a new Nucleus 6 microphone cover is a simple way to keep track. Over a year you will see how quickly your covers clog and can reorder in good time.

Is a replacement Cochlear Nucleus 6 CP910 Microphone Cover safe for my CP910 or CP920?

These are third-party compatible covers, not a product made by Cochlear. They have the same size and shape as the protectors they replace, so they sit over the Nucleus 6 microphone openings in the normal way, and the removal tool is shaped for the same job.

We check every pack before dispatch. If the covers or tool arrive defective, do not fit, or are the wrong item, we replace them or refund you. If you want reassurance first, send a photo of your processor on WhatsApp.

Bilateral and family tips for Nucleus 6 covers

If you wear two Nucleus 6 processors, change the covers on both at the same time. Sound stays balanced between your ears and you will not spend days wondering why one side seems dull.

For children, check the covers more often. Sand, food, sun cream and play all clog them faster, and young children may not be able to say that sound has changed. A quick look at drop-off and pick-up is enough.

Keep one spare set in a small labelled bag with the removal tool, and a second in a travel kit. A Cochlear Nucleus 6 CP910 Microphone Cover weighs almost nothing, and having one to hand turns a dull-sounding day into a two-minute fix.

How often should you replace the Cochlear Nucleus 6 CP910 Microphone Cover?

Microphone covers are small filters, and filters clog. Dust, skin oil, hair spray, sweat and rain slowly block the tiny holes in the cover, and the microphones behind it hear less. Most clinics suggest changing the Cochlear Nucleus 6 CP910 Microphone Cover about every three months, and sooner if you work outdoors, play sport, live somewhere dusty or humid, or notice sound getting dull. Marking the date on a calendar or phone reminder is the easiest way to keep on schedule. Because each pack holds several covers, one pack lasts many months.

Signs your microphone covers are blocked

• Voices sound muffled or far away, as if someone is talking through a wall.
• Speech is harder to follow in noise than it was a few weeks ago.
• Your own voice sounds different or quieter.
• You see dirt, a dark film or moisture spots on the cover.
• Your audiologist finds the microphone test weaker than before.

If you notice any of these, change the Cochlear Nucleus 6 CP910 Microphone Cover first. It is the cheapest and fastest fix, and it often brings sound back to normal straight away. If sound is still poor with fresh covers, contact your clinic so they can test the processor.

Microphone cover care between changes

You do not need to clean the Cochlear Nucleus 6 CP910 Microphone Cover with water or alcohol; doing so can push dirt deeper into the filter. Instead, wipe the outside of the processor with a soft, dry cloth every evening, and store the Nucleus 6 processor in a drying box or dry kit overnight if you sweat or live in a humid climate. Keep hair products, sun cream and make-up away from the processor top. When you swim or shower, take the processor off unless you use a waterproof cover made for it.

Who uses the Cochlear Nucleus 6 CP910 Microphone Cover most

Children wear through microphone covers faster because of play, sand, food and sweat, so parents often keep a spare pack in the school bag. Adults who work in workshops, farms, kitchens or building sites also change covers more often. Runners, cyclists and gym users see sweat clog the filters within weeks in summer. If you use your Nucleus 6 with a telecoil, streaming or a remote microphone, clean microphone covers still matter, because the processor mixes the microphone sound with the streamed sound.

Buying checklist for the Cochlear Nucleus 6 CP910 Microphone Cover

• Check your processor model on the side of the Nucleus 6 body before you order.
• Order more than one pack if you have two processors (bilateral) or a child who is very active.
• Add a drying box if you live somewhere humid; it helps the new covers last longer.
• Keep your order email: it has your tracking number and our WhatsApp contact for fitting help.
